Hauv kev tshuaj xyuas cov pej xeem ntawm cov koom haum qhov teeb meem ntawm kev teeb tsa pej xeem ciam teb yuav tsum tau xav txog. Ib qho ntawm cov kev siv dav tshaj plaws ua raws li los ntawm kev ua haujlwm pioneering ntawm Hannan thiab Freeman (1977).
Tsuas yog li ntawd, qhov kev xav ntawm pej xeem ecology yog dab tsi?
Population ecology txoj kev xav qhia tias kev hloov pauv tshwm sim ntawm qhov pej xeem qib. thiab yog qhov tshwm sim ntawm cov txheej txheem ntawm kev xaiv thiab hloov pauv (Carroll, 1988). Ib lub koom haum ib leeg txoj sia nyob yog nyob ntawm kev xaiv ib puag ncig ntawm cov ntawd.
Tom qab ntawd, lo lus nug yog, cov pej xeem ecology puas muaj txiaj ntsig zoo rau kev kawm ntawm cov koom haum? Pej xeem ecology yog ib qho tseem ceeb tam sim no paradigm nyob rau hauv lub sociological kawm txog cov koom haum . Cov exponents ntawm txoj kev xav no siv lub tswv yim, theories, txoj kev, thiab cov qauv muab tau los ntawm kev lom neeg. kawm ntawm kev hloov pauv ntawm cov nroj tsuag thiab tsiaj txhu rau "cov neeg" ntawm cov koom haum.
Tsis tas li lo lus nug yog, dab tsi yog pej xeem ecology hauv kev lag luam?
Pej xeem ecology yog kev kawm txog kev hloov pauv hloov hauv ib pawg ntawm cov koom haum. Cov koom haum uas dhau los ua tsis sib haum nrog ib puag ncig thaum kawg tau hloov pauv los ntawm kev sib tw nrog cov koom haum tshiab zoo dua rau cov kev xav tau sab nraud.
Vim li cas thiaj tseem ceeb rau kev kawm txog pej xeem ecology?
Pej xeem ecology yog tseem ceeb nyob rau hauv kev txuag biology, tshwj xeeb tshaj yog nyob rau hauv txoj kev loj hlob ntawm pej xeem Kev soj ntsuam kev muaj sia nyob (PVA) uas ua rau nws muaj peev xwm kwv yees qhov yuav tshwm sim ntev ntawm ib hom kab mob nyob hauv ib thaj chaw nyob.

Leej twg tsim txoj kev xav ntawm kev laus?
Txoj kev xav ntawm kev laus qhia tias cov neeg laus muaj kev zoo siab tshaj plaws thaum lawv nyob twj ywm thiab tswj kev sib raug zoo. Txoj kev xav tau tsim los ntawm Robert J. Havighurst raws li cov lus teb rau qhov kev xav ntawm kev laus
Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Dab tsi yog kev faib cov pej xeem hauv ecology?
Hauv ecology, cov pejxeem muaj tag nrho cov kab mob ntawm ib hom tsiaj uas nyob hauv ib cheeb tsam. Cov pej xeem kuj tuaj yeem piav qhia txog kev faib tawm, lossis kev faib tawm, ntawm cov tib neeg uas tsim nws. Cov tib neeg tuaj yeem muab faib ua ib qho sib xws, random, lossis clumped qauv
Dab tsi yog pej xeem ecology hauv kev lag luam?
Population ecology yog kev kawm txog kev hloov pauv hloov pauv hauv ib pawg ntawm cov koom haum. Siv cov pej xeem raws li lawv theem ntawm kev tsom xam, cov pej xeem ecologists txheeb xyuas qhov kev yug thiab kev tuag ntawm cov koom haum thiab cov koom haum cov ntaub ntawv nyob rau hauv cov pej xeem nyob rau lub sij hawm ntev
